Mathematics

sammy [17]3 years ago

Answer:

Option D

Step-by-step explanation:

In the first three options we can evaluate the values of x with the help of Sine Rule for all the triangles

The Rule says

\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}

Where a , b and c are the sides opposite to the angles A, B and C of any ΔABC.

Hence , in order to determine unknown values of sides or angles , we need any 3 values from all 3 sides and 3 angles in a triangle. First Three options give us three values but the last option gives only 2.

Example

in first option we can apply Sine Rule as

\frac{\sin 84}{x}=\frac{\sin 63}{3}

\frac{0.994}{x}=\frac{0.891}{3}

x=\frac{0.991 \times 3}{0.891}

x=\frac{2.973}{0.891}

x=3.336

Solve for x. x - 2(2 - 3/2 x) = 2(4 - x) + 1
STALIN [3.7K]

Answer:

x = 13/6

Step-by-step explanation:

We are the following expression;

       x - 2(2 - (3/2)*x) = 2(4 - x) + 1

       x - (4 - 3*x) = 8 - 2*x + 1

       x - 4 + 3*x = 8 - 2*x + 1

         4*x + 2*x = 9 + 4

             6*x = 13

              x = 13/6

The area of a rectangle is 5/8 meter. The length of the garden is 1/5 meter. What is the width of the rectangle?
Afina-wow [57]

Width of rectangle is Width=\frac{25}{8} meters

Step-by-step explanation:

Area of rectangle = \frac{5}{8}

Length of garden = \frac{1}{5}

Width of rectangle = ?

Using the Formula:

Area = Length * Width

Putting values and finding width:

\frac{5}{8}=\frac{1}{5}*Width\\ Width=\frac{5}{8}\div\frac{1}{5}\\Width=\frac{5}{8}*\frac{5}{1}\\Width=\frac{25}{8} meters

So, width of rectangle is Width=\frac{25}{8} meters

Astronomers treat the number of stars in a given volume of space as a Poisson random variable. The density in the Milky Way Gala
umka21 [38]

Answer:

a) 0.264

b) 48 cubit light-years

Step-by-step explanation:

For calculating a)  What is the probability of 3 or more stars in 16 cubic light years?

a)

λ= 1 star/16 cubic light-years

t= measure t in units of 16 cubic light years.

E(Y) = λ t = (1/16)(16) = 1 star

P(X>=2) = 1 - P(X<2)

= 1 - [e^-1 + (e^-1)(1)/1!]

= 0.264

b)

P(X≥1) = 1 - P(X=0)

= 1 - e^-μ

0.95 = 1 - e^-μ

e^-μ = 1 - 0.95

e^-μ = 0.05

ln(e^-μ) = ln(0.05)

-μ = -3

μ = 3

Therefore  3 x 16 = 48 cubic light years of space

Someone plz help me with this question with an explanation
Furkat [3]

To use the angle-angle similarity theorem you need to know 2 corresponding angles of each triangle are the same.

You are already shown that angles H and M are the same.

The sets of corresponding angles are:

H and M, N and I, and O and J

The answer would be angle O and angle J are similar.
